how do you determine the thermal energy of an object
Answer:
An object's thermal energy is dependent upon its temperature and mass. The higher the temperature of a given quantity of a substance, more is its thermal energy. Similarly, for the same temperature, higher mass of a substance will contain more thermal energy

how do ions form bonds, and describe the structure of the resulting compound.
Answer:
Electrons are transferred between atoms together in the ionic compound. The ions are arranged in a regular repeating pattern in an ionic crystal
Explanation:
Ions electrostatically attracts its counter ions and forms the ionic bond between these ions. The structure of ionic compounds depends on the number of atoms and bonded pair of electrons.
What is ionic bonding ?Ionic bonds are formed between metals and non-metals. Metals are electron rich and easily loss one or more electrons to the electron deficient non metals.
The loss of electrons make the atom forms a positive ion called cations. The gain of electrons make the formation of anions or negative ions. These positive ions and negative ions attracts electrostatically and forms ionic bond between them.
The structure of ionic compounds depends on the number of bonded atoms, size, presence of lone pairs etc. In solution ionic compounds exists as separate ions.

We can use the formula M₁V₁ = M₂V₂ the total volume of water that will yield 0.800 M HCl. We can then subtract that from the initial volume to get how much water needs to be added.
Since M₁V₁ = M₂V₂ (starting mole× starting volume = end mole × end volume)
⇒ (5 mol)(20 mL) = (0.80 mol) V₂
100 mol/mL = 0.8 mol × V₂
⇒ V₂ = 100 mol/mL ÷ 0.8 mol
= 125 m
Since we began with 20.0 mL of water,
water needed to add = 125 mL - 20 mL = 105 mL
Which option correctly describes the pattern of valence electrons on the periodic table? (1 point)
o The number of valence electrons increases from right to left.
O The number of valence electrons increases from left to right.
O The number of valence electrons increases from bottom to top.
O The number of valence electrons increases from top to bottom.
Answer:
The number of valence electrons increases from left to right.
Explanation: The number of valence electrons increases going across a period, or row in the periodic table, for example, group 1 elements have 1 valence electrons and group 2 elements have have 2.

A. Atoms of the same element can have different masses
B. The nucleus of an atom has a positive charge
C. Atoms of isotopes of an element have different numbers of protons
D. Atoms are mostly empty space

Answer:
That would be a community.
Explanation:
A field of many different species of wildflowers is considered to be a community.
What is community in biological terms?It is called biological community meaning an interacting group of various species sharing a common location.Factors which determine overall structure of community are number of species, abundance of each species,interaction among the species and community's ability to return to normal after a natural calamity.
Change of communities over a period of time is called as ecological succession.Each species in a community has its own characteristic niche . The niche includes all the interactions of the species with other members of the community.An ecosystem comprises of biological community together with its physical environment.

In terms of attractive forces, explain why LiClhas a higher melting point than SCI2.
Answer:
Well, SCl2 is known, so is disulfur dichloride… Cl−S−S−Cl …and BOTH these species are molecular… On the other hand, lithium chloride, an ionic salt, is decidedly non-molecular, and consists of an infinite array of lithium and chloride ions held together by strong electrostatic forces ….. and thus we would expect the salt to have the much higher melting point….
